DUMP-WAGON.

SPECIFICATION forming part of Letters Patent No. 377,331, dated January 31. 1888.

Application filed Octobcr 20, 1857. Serial No. 252,874. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE \V. RICHARD- SON, a citizen of the United States, and a resident of Chicago, county of Cook, State of Illi- 5 nois, have invented new and useful Improve- Inentsin Dump-\Vagons, of which the following is a specification, reference being had to the accompanying drawings, illustrating the invention, in which- Figure 1 is a side elevation of a dumpwagon in which my invention is embodied; Fig. 2, a top or plan view of Fig. l with the wheels removed; Fig. 3, an end elevation of Figs. 1 and 2, looking in the direction indir5 cated by dart Z; Fig. 4, a front elevation of Fig. 2, looking in the direction indicated by dart Y; Fig. 5, an enlarged view of one of the rings which hold the operating-levers in place. This invention will be fully understood from the following description.

A A represent the sides, B the rear end, and O the front end, of the box.

(2, Figs. 1, 2, and 4, is a fixed bottom in front of the box, and 99 are side-boards to it, one of which is removed at Fig. l, more clearly to show the parts.

D represents a shaft, which is preferably of hollow iron, extending longitudinally and 0 centrally through the bottom box and over the fixed bottom (I, and it is held in position by a metal collar, X, at each end, and to the front end of the shaft D is affixed a plate, I), and to the plate are affixed two levers, c c, and 5 to the under side of the shaft D are affixed stiff downwardly-projectin g prongs V V V V IV, for the purpose of elevating the dumpbottoms G at, the prong \V being curved, that it may be out of the way of the front wheel, U. The dump-bottoms G are hinged to the shaft D at E, and the bottoms m, on the opposite side of the shaft, are hinged to it at F, as shown at Figs. 2 and 3. A rod, I, lying inside and close to the bottom of both 5 side-boards A A, has bearings in the endboard 13 C, so thatitmay be turned by an upwardly-projecting endpart, c. The sides of the rods I are provided with pins a a a, &c.,

to support the free edges of the dump-bottoms m G. The links f, Figs. 1, 2, 4, and 5, are put over the upward-projecting parts 0 of the rods I, to hold the pins a level.

At Figs. 2 and 3 the bottoms G are represented as resting on the pins (4, and the bottoms m are shown to be swung down as when a load is to be dumped. The bottoms G m are allowed to fall down by removing the rings], which will, by the weight of the load on the bottoms, bring the projecting parts 6 in positions shown by dotted lines 19, Fig. 4, and the pins will project downward. The bottoms are elevated by turning the levers c 0, so as to bring the prongs V \V to horizontal positions, and the bottoms are then locked by turning the parts e e to vertical po- 6 sitions and securing them by the links ff. The reason for the two levers c is to have one 'lever at all times in convenient position for use.

It is necessary in this kind of a wagon to have the bottom of the box well up from the axle-trees, for generally small wheels, T U, are employed, and also to have the box strongly supported.

N is the rear axle-tree, and L is the bol- 7 5 ster, between which and the axle-tree is placed the lower portion, M, of a bar of iron, which extends up on and is fastened to each side of the box, as shown at J J, and passing over the bolster L, at each end, is a strap of iron, O, which, by nuts and bolts K, is secured to a brace, Q S, whose top ends are secured to the box A. By this means the axle-tree bol ster and box attachment is suificiently strong to support the great weight required in hauling broken stone and coal, and at a proper height for the box to clear its dumped load. The forward bolster is secured by a similar support, 0 K, to the turn table 2' a, which gives to the forward connection suitable 0 strength.

I claim and desire to secure by Letters Patcnt 1. In dumpingwagons, the box A B O, combined with-the longitudinal central shaft, 5 D, with the hinged bottoms G at, the shaft provided with the prongs V W, in combination with the levers c c, for elevating the bot- S Q, substantially as and for the purpose specitoms, as specified.
